How do you calculate entropy from microstates and how does increasing the volume of the system affect calculating microstates?
What was the concentration, in mol/L and mg/L, of Cu^2+ and Zn^2+ in the original solution? If the solution was prepared by dissolution of 0.654 g of brass in 250.00 mL solution, what the percentage of copper and zinc in the original sample of bra..
A mixture initially contains A, B, and C in the following concentrations: [A] = 0.650 M, [B] = 1.35 M, and [C] = 0.300 M. The following reaction occurs and equilibrium is established: A+2B C
Three solutions are mixed together to form a single solution. One contains 0.2 rm mol rm Pb(CH_3COO)_2, the second contains 0.1 rm mol rm Na_2S, and the third contains 0.1 rm mol rm CaCl_2.
A flask contains only H2 at 59.2 atm and I2 (g) at 118. atm. The contents are then allowed to come to equilibrium according to the equation H2 (g) + I2 (g) 2HI (g) , Kp = 50.5
